AUTOMATIC ADVERTISING DEVICE.

SiPEQIE'ICATION forming part of Letters Patent No. 319,597, dated June9, 1885.

Application filed May 3, 1884.

To all whom it may concern.-

Be it known that I, JOHN MOGREER,a citizen of the UnitedStates, residingat Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Automatic Advertising Devices, ofwhich I do declare the following to be a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My present invention has for its object to provide an improvedconstruction of advertising device, whereby a series of pictures orother attractive cards may be successively and automatically displayedin connection with advertisements to which the attention of the publicwill thus be directed. This object I have accomplished by the mechanismhereinafter described ,and illustrated in the accompanying drawings, theinvention consisting in certain details of construction, to beparticularly defined in the claims at the end of the specification.

Figure 1 is a view in front elevation of my improved advertisingdevice,parts being broken away for the purpose of better illustration.Fig. 2 is a side view with parts broken away. Fig. 3 is an enlargeddetail view, in longitudinal section,of the display-drum and connectedparts. Fig. 4 is a sectional view on line 09 w of Fig. 3. Fig. 5 is atransverse sectional view of the drum, aportion of one end being brokenaway to show subjacent parts. Fig. 6 is a detail view, in transversesection, of one of the cards and its sustaining-rod.

Like letters of reference denote corresponding parts in the severalviews of the drawings.

A designates the main casing, the front A of which is cut away, asshown, to form an opening through which the cards may be seen. Withinthis casing, at a point about opposite the center of the front opening,is placed the display-drum B,that is sustained by means of the shaftG,having its ends journa1ed,respectively,in one side of the casing andin the journal-block 0, attached to opposite side. The

drum 13 consists, preferably,of a paper cylinder having its exteriorsuitably ornamented, and having the heads b, to which are attached theplates D D, that project beyond the periphery of the drum, and areprovided with (No model.)

the perforations d, to receive the rods E, that enter the pockets formedby the strips f, at

- tached to the cards F, and thus serve to hold the cards securely uponthe drum. Perforat-ions d are also formed in the end of the plate D, toreceive staples d, that fit over the bent ends of the rods and retainthem in place. From this construction it will be seen that in order tosecure the cards upon the drum it is only necessary to withdraw thestaples d and slip backward the rods until out of the plate D,when theirfree ends may be thrown outward, and the cards may be placed thereon.

Each of the cards F is provided,preferably, upon one side with a pictureto attract the eye, and upon the opposite side with an advertisement, sothat as the drum revolves the card will successively display the pictureand the advertisement.

Upon the side of the plate D is pivotally held the pawl 9, that ispressed downward by the spring 9, and engages with the ratchetwheel G,attached to the end of the cord-pulley H, that iskeyed to the shaft C.

To the opposite end of the pulley H is connected the ratchet-whecl H,with which engages the pawl I, that is carried by the main cog-wheel l,loosely journaled on the shaft 0, and held in place by means of thewasher i. A pinion, K, the shaft of which is journaled in the frame 7a,engages with the cog-wheel I, and to the shaft of this pinion is keyedthe escapement ratchet-wheel L, the movement of which is controlled by asuitable double escapement-pawl carried by the upper end of the weightedpendulum-rod L.

A cord, M, having one end secured to the cord-pulley H, passes throughthe top of the casing over the pulley N, and sustains the weight O,thatserves to impart the movement to the display-drum necessary to bring thecards before the opening of the casing.

Upon the end of the shaft 0 farthest from the escapement mechanism isplaced the ratchet-wheel P, that is connected to the plate D, thisratchet wheel and drum being loosely journaled on the shaft 0, and apawl, 1?, piv otally connected by the screw 1) to the side of thecasing,engages with this ratchet and serves to prevent any backwardmovement of the drum. The cards F are made of such size that as the drumrevolves each card will successively strike the top of the frontopening, and will be detained thereby, thus showing the picture untilthe, drum has traveled a sufficient distance to permit it to drop anddisplay the advertisement upon the reverse side.

From the foregoing description the operation will be seen to be asfollows: A crankkey is applied to the squared end of the main shaft, andby turning this key the weight-cord is wound upon the cord-pulley H.During this operation the ratchet-wheel P and pawl P prevent thebackward movement of the drum. The force of the weight,when wound up,tends to turn the cord-pulley,whieh communiea'tes motion to the drum bythe ratchetwheel G and the pawl'g. The ratchet-wheel H, engaging withthe pawl I, turns the cog: wheel I; but the movement of the cog-wheel,and consequently of the cord-pulley and drum, is-controlled by thedouble pawl of the pendulumand by the escapement ratchet-wheel andpinion. It will thus be seenthat the displaydrum is caused to slowlyrevolve to bring the cards before the front opening of the casing.

I am aware that it has been heretofore proposed to construct anautomatic advertising Having thus described my invention, what I claimas new,and desire to secure by Letters Patent, is

1. In an advertising device, the combina- 5 tion, with theinclosing-case having a sightopening, and with the display-drum havingthe perforated end plates projecting beyond its periphery,of rodspassing through said end plates and removably held therein, substanotially as described.

2. In an advertising device, the combination, with the display-drum,ofthe perforated end plates,-the rods removably held in said endplates,and the cards having each apocket 5 to receive a rod,substantially as described.

' 3. In an advertising device, the combination, with the drum having theperforated end plates projecting beyond its periphery,of the removablerods having bent ends and staples 50 for holding said ends,substantially as described. I

4. In an advertising device, the combination of the drum B, the shaft 0,the ratchetwheel P, the pawl P, the ratchet-wheel Gand 5 pawl g, thecord-pulley H, the cord M, the weight O,and the escapement mechanism,substantially as described.
